CVE-2026-90130

CVE-2026-90130 is a Linux kernel vulnerability in the vdpa_sim module. When kthread_run_worker() fails during device creation, vdpasim_create() leaves vdpasim->worker as an ERR_PTR . The subsequent error path releases the partially initialized simulator, and vdpasim_free() unconditionally pass...

CVE-2026-90130 vdpa_sim: fix cleanup after worker creation failure

In the Linux kernel, the following vulnerability has been resolved: vdpasim: fix cleanup after worker creation failure vdpasimcreate leaves vdpasim-worker as an ERRPTR when kthreadrunworker fails. The error path then drops the device reference, which releases the partially initialized simulator...
